In this free online course, you will discover how customer requirements and airworthiness regulations are used to determine the important aspects and tasks to be performed in aircraft conceptual design. The typical constraints in a transport aircraft including the maximum cruise Mach number, climb rate, and stalling speed as well as the forms of airworthiness requirements will be dissected. You will study Raymer’s big six parameters and other important performance parameters which are used to estimate the component configurations of an aircraft via mathematical calculations. You will see the step-by-step approach for the constraint analysis of the tensile properties of the components of an aircraft in the missed approach gradient and take-off climb gradients. The typical constraint analysis of a military aircraft will also be discussed with reference to the quoted values from the historical data of an actual aircraft. Then, you will consider the procedures and steps for refined sizing and methods for fixed engine sizing. The various costs incurred at the conceptual design phase of aircraft fabrication will be examined and this segment will conclude with the FALCCM model for fighter aircraft lifecycle costs estimation.

Next, the range payload diagram will consider the trade-off between the range and payload. You will examine the technical breakdown of an aircraft weight from the analysis of certain parameters determined by aircraft manufacturers and airliner operators. The aircraft range will then be classified into the harmonic range, ferry and gross still range from the component parameter values. The environmental problems posed to the living environment by the aviation industry, in general, will be inquired. The subject on key environmental issues will address air pollution and noise pollution which are the major environmental issues of concern. The negative impact of the emissions and particulate matter that causes air pollution and the damaging effects of noise pollution will be discussed. Then, the concepts and model for pollution assessment and noise management will be highlighted. Noise contour studies will employ the aviation environmental design tool to model the noise and emission levels and create the contour maps of the different noise zones. The aircraft noise pollution reduction technologies and will consider concepts such as engine shape optimization, use of engine acoustic liners, noise airframe reduction, and other operational changes that will help to minimize the cacophony in the environment.

The v-n diagram is applicable for symmetrical manoeuvres in the vertical plane, which depicts the region where it possesses its highest numerical value. The load factors and upper load limits for the vertical plane will be outlined. The effects of gusts, gust loading lines and limit envelope will be presented and a performance equation will be proposed for the parameter value estimations. You will also consider the different forms of loads from the wave vortex shedding of large aircraft. High altitude long endurance aircraft studies will include its use in satellite communication, military and non-military aerial surveillance and research. Also, morphing configuration studies will focus on the reasons for morphing, the benefits and challenges, and the structural components and technologies like telescopic wings, actuators and sensors for achieving morphing. You will also learn about the advantages and disadvantages of inflatable wings and the application of rigidization for aircraft wing structures. The topic on the effects of technological advancements in warfare will discuss the various types of combat aircraft, design functions and operations and weapon systems for mission objectives. The terminal and non-terminal threats of an attack aircraft will be outlined while the mission threat analysis and effectiveness of an aircraft weapon system will be assessed via the measure of mission success.
